In brief: Very different
An eeg tells the definitive difference because they have different brain wave patterns.
But clinically petit mal are absence seizures where the person just blanks out for a second and then starts up like nothing happened. Grand mal involves the whole body in what is called tonic-clonic where arms and legs twitch and convulse. Eyes roll back in head, loss of consciousness.
